It runs fine for a couple minutes at wot then dies , It will stay running at wot as long as I keep filling the fuel bulb. Just got this from a dealer that used it an a rental pontoon boat and said the vst was just done, If this is true then I figure I must have a problem between the fuel tank and the motor , fuel line on tank is new and the lines on the motor look fine , I am going to replace the check valve on the fuel tank and see if that is the problem , my question is does this model have a lift pump on it or that just on bigger motors.
